Benefits of technology

The present invention provides a navigation apparatus and a navigation server that can update navigation map information based on the actual state of a road, such as opening or closure, and the user's purpose. The navigation apparatus recognizes differential information between the navigation map information and a support map information stored in the navigation server, and transmits the index information tagged to the objective differential information to the navigation server. The navigation server determines the temporal validity of the objective differential information and adds it to the navigation map information. This allows the navigation apparatus to guide the mobile object along an appropriate navigation route in consideration of the road environmental state. The invention reduces the communication amount of information between the navigation apparatus and the navigation server, and improves the user's experience.

Problems solved by technology

However, in fact, a road may not be opened to traffic even after the scheduled date or may be closed earlier than scheduled due to some reasons.
Thereby, if the navigation map information has been updated according to the scheduled opening date or closure date of the road, there will be a problem that the navigation map information stored in the navigation apparatus may become different from the actual road state.
Furthermore, an automobile which is traveling along a route set by the navigation apparatus may get involved in a traffic congestion due to the reason that a road which has actually been opened to traffic cannot be used.

Embodiment Construction

[0022]Hereinafter, an embodiment of a navigation apparatus and the like of the present invention will be described with reference to the drawings.

[0023]The configuration of a navigation system of the present invention will be described with reference to FIG. 1. The navigation system is composed of a navigation server 100 and a navigation apparatus 200 mounted in an automobile 2. The navigation apparatus 200 may also be mounted in a mobile device other than an automobile or ported by a user (one type of the mobile object).

[0024]The navigation server 100 is composed of one or plural server computers. The navigation server 100 is provided with a first road traffic information storing element 101, a second road traffic information storing element 102, a weather information storing element 103, a support map storing element 104, an update record storing element 105, a first support processing element 110, and a second support processing element 120.

Abstract

In a navigation system, an index information (idx(di(S))) tagged to an objective differential information (di(S)) which is a part of the entire differential information (di) is transmitted from a navigation apparatus (200) to a navigation server (100). Specifically, the index information (idx(di(S))) tagged to the objective differential information (di(S)) pertained to an area (S) containing therein a navigation route (r) for guiding an automobile (2) to a destination position (p2) is transmitted from the navigation device (200) to the navigation server (100). Further, the navigation server (100) determines whether the objective differential information (di(S)) is temporally valid or not, and the objective differential information (di(S)) is added to a navigation map information on condition that the determination result is affirmative. Furthermore, a new navigation route (r) can be set and output according to the updated navigation map information to which the objective differential information (di(S)) has been added.
